         Re: MetLife Insurance Company of Connecticut
             Form S-1 Registration Statement
             Post-Effective Amendment No. 6 under the Securities Act of 1933
             File No. 333-147912
             ---------------------------------------------------------------

Dear Sir or Madam:

         On behalf of MetLife Insurance Company of Connecticut ("MICC"),
transmitted herewith for filing with the Securities and Exchange Commission
("Commission"), pursuant to the requirements of Section 10(a) of the Securities
Act of 1933, as amended (the "1933 Act"), and Rule 101(a) of Regulation S-T, is
a conformed electronic format copy of Post-Effective Amendment No. 5 (the
"Amendment") to the above-referenced Registration Statement on Form S-1 under
the 1933 Act with respect to the MetLife Retirement Account deferred variable
annuity contracts issued by MICC which have a market value adjustment feature.
The Amendment contains, pursuant to Rule 429 under the 1933 Act, a combined
prospectus and will act, upon effectiveness, as a post-effective amendment to
the registration statement under Commission File No. 333-69793. The Amendment is
marked to show the differences between it and Post-Effective Amendment No. 5 to
the above-referenced Registration Statement filed on April 8, 2010 ("Prior
Amendment").

         The purpose of the Amendment is to respond to SEC staff comments
provided orally on April 13th and 15th, 2010.

         MICC requests, pursuant to Section 8(c) of the 1933 Act, that the
Commission declare the Amendment effective May 3, 2010, or as soon thereafter as
practicable.

         We are providing the Commission staff a courtesy copy of the Amendment,
marked to show the differences between it and the Prior Amendment.



         This transmission contains conformed signature pages, the manually
signed originals of which are maintained at MICC's offices.

         Please contact the undersigned at 202-778-9886, Andras P. Teleki at
202-778-9477, or Brian M. Johnson at 202-778-9296 with any questions or
comments.

                                    Sincerely,



                                    /s/ Diane E. Ambler
                                    -------------------
